Space-Based Multisignature Wallet Technology

Enables ultra-secure transactions for financial services like digital currency exchanges, wallet providers, and enterprise custody solutions.

Our Flagship Application

Multisignature refers to a digital asset security feature that requires multiple keys to authorize a cryptocurrency transaction rather than a single signature from one key. It adds layers of security to protect your digital assets.

To enable even greater security, SpaceChain has developed the world’s first space-based multisignature authentication service that allows users to validate their transaction through the satellite.

One of the private keys is generated after the space node is launched into orbit. It is saved in the space node during the whole service period and cannot be transmitted. This key is signed by the satellite to complete the transaction. 

The risk of physically destroying the space node is reduced greatly as it runs on orbit around the earth. In addition, the measurement, control and data transmission of the space node uses the aerospace-specific code encryption protocol and communication band, making the data hard to decrypt.
